Benefits of technology

[0009] (2) It provides reliable embodiments. A guiding rail is introduced into the package of shoe covers. Shoe covers in the package shifts along the guiding rail in a sequential order during application.

Problems solved by technology

It is virtually impossible to pack hundreds of such shoe covers nicely flat into storage box.
It is also very difficult to dispense packed shoe covers in a sequential order because two neighboring units stick frequently to each other in a movement.
How to pack and dispense shoe covers is an unsolved problem.
Unfortunately, Khozai, while suggesting hanging features, failed to understand the nature of elastic band.
Gultekin et al, still, fails to understand the nature of elastic band.
The long-felt problem of shoe cover packaging remains unsolved.

Embodiment Construction

[0016]FIG. 1 illustrates the principle of the invention showing 8 units of shoe covers penetrated by a pair of pins.

[0017] Shoe covers 200 are made with disposable flexible fabrics in a size capable of receiving the largest shoes. Each unit of shoe covers 200 has an opening 120 and an elastic band 100. Elastic band 100, made with rubber strip, should be stretched substantially while being sawed along opening 120. It is a common knowledge to understand how elastic band 100 works. In storage, elastic band 100 constrains opening 120 and shoe covers 200 into an irregular wrinkle configuration. During application, an external force, hands or device, expands opening 120 widely open for receiving a shoe of any sizes. After being released from the external force, elastic band 100 constrains opening 120 smaller and secures the coverage of the shoe inside.

[0018] The key element of the invention is the introduction of a shifting member into the package. In FIG. 1 of the preferred embodiment,...

Abstract

A shifting rail is introduced into a package of disposable shoe covers for facilitating dispense of shoe covers onto shoe cover application devices. The shifting rail engages with each unit of shoe covers in the package sequentially. During application, shoe covers shift along the rail in sequential order towards the shoe cover application device.

Description

BACKGROUND OF THE INVENTION [0001] Shoe covers are widely utilized in a variety of fields, such as laboratories, medical operating rooms, animal rooms, house keeping works, and real estate industries, etc. For protection purposes, these shoe covers are usually made with disposable material in a simple and low cost manner to avoid repeat usage. In order to fit all shoe sizes ranging from the largest to the smallest, shoe covers are usually made with flexible fabrics for the largest shoe sizes. A rubber-like elastic band is then employed to constrain the flexible fabrics for fitting to the smallest shoe sizes. [0002] Shoe covers made with elastic band and flexible fabrics are naturally curved in irregular wrinkle configuration. It is virtually impossible to pack hundreds of such shoe covers nicely flat into storage box. It is also very difficult to dispense packed shoe covers in a sequential order because two neighboring units stick frequently to each other in a movement. Therefore, m...
